Some thoughts:
1) Has your W always been like this? If so, your recent irritation over this is probably just seeping out from other areas of irritation. (You didn't tell us you were married to Jessica Simpson ) I must say, sounds like a real Mars/Venus thing to me. You are being very rational and "fix-it" logical; she doesn't know (and doesn't want to know)what's wrong with it, just wants to hand it over to you.

2) If this is new behavior on her part, I would bet on it being either A) clinical depression (affects memory and brain function, would explain some of the compulsive shopping) or B)early dementia (is she making mistakes and errors in other ways? History of Alzheimer's in the family?)
